ABSTRACT

Myeloperoxidase inhibitors, pharmaceutical compositions containing such inhibitors and the use of such inhibitors to treat, for example, cardiovascular conditions.

BACKGROUND OF THE INVENTION

This invention relates to compounds that are myeloperoxidase inhibitors,pharmaceutical compositions containing such inhibitors and the use ofsuch inhibitors to treat for example, cardiovascular conditionsincluding acute coronary syndrome.

Myeloperoxidase (MPO) is a heme-containing enzyme belonging to theperoxidase superfamily. Examples of animal peroxidases arelactoperoxidase, thyroid peroxidase, eosinophile peroxidase andmyeloperoxidase. Myeloperoxidase is present in primary granules ofneutrophils and to a lesser extent in monocytes. It catalyzes thesynthesis of hypochlorous acid from chloride and hydrogen peroxide. Thehypochlorous acid formed is a powerful oxidant that reacts with avariety of cellular substrates including heme proteins, porphyrins,thiols, iron sulfur centers, nucleotides, DNA, unsaturated lipids,amines and amino acids.

In addition, MPO-catalyzed reactions and their products have been foundto exhibit pro-atherogenic biological activity during the development ofatherosclerosis and cardiovascular disease. For example, themyeloperoxidase plasma content is correlated with the appearance ofcardiovascular disorders in patients suffering unstable angina pectoris.Myeloperoxidase has been reported to contribute to the development ofatherosclerosis by the oxidation of lipid and protein in LDL and HDL.

Furthermore, it has been observed that MPO-generated oxidants reduce thebioavailability of nitric oxide, an important vasodilator. Accordingly,high MPO plasma levels are inversely correlated with the success oftherapy to establish reperfusion of occluded arteries. High MPO levelsare also associated with decreased survival from congestive heartfailure. Additionally, it has been shown that MPO plays a role in plaquedestabilization which leads to plaque rupture and myocardial infarction.

Therefore, MPO is thought to play a role in several processes that leadto cardiovascular disease including 1) impaired cholesterol traffickingand progession of the atherosclerotic plaque towards an unstable state,2) destabilization of the atherosclerotic plaque and plaque rupture, 3)consumption of nitric oxide leading to impaired endothelial function andflow, and 4) pathological tissue damage post ischemia contributing toatrial fibrillation and adverse cardiac remodeling with left ventricularhypertrophy leading to congestive heart failure. As such inhibitors ofMPO activity are proposed to offer significant therapeutic benefit inthe prevention and treatment of cardiovascular disease.

Nevertheless, although MPO has been implicated extensively in theetiology and progression of cardiovascular disease, a biologically safeand non-toxic inhibitor of MPO has yet to be developed. Accordingly,there remains a need for pharmaceutical agents that have myeloperoxidaseinhibiting activity and are useful in the treatment, prevention ordiminution of the manifestations of the maladies described herein.

For areview on suitable salts, see Handbook of Pharmaceutical Salts:Properties, Selection, and Use by Stahl and Wermuth (Wiley-VCH, 2002).

The compounds of the invention may exist in both unsolvated and solvatedforms. The term ‘solvate’ is used herein to describe a molecular complexcomprising the compound of the invention and one or morepharmaceutically acceptable solvent molecules, for example, ethanol.Such solvent molecules are those commonly used in the pharmaceuticalart, which are known to be innocuous to the recipient, e.g., water,ethanol, and the like. Other solvents may be used as intermediatesolvates in the preparation of more desirable solvates, such asmethanol, methyl t-butyl ether, ethyl acetate, methyl acetate,(S)-propylene glycol, (R)-propylene glycol, 1,4-butyne-diol, and thelike. The term ‘hydrate’ is employed when said solvent is water.Pharmaceutically acceptable solvates include hydrates and other solvateswherein the solvent of crystallization may be isotopically substituted,e.g. D₂O, d₆-acetone, d₆-DMSO. The term “hydrate” refers to the complexwhere the solvent molecule is water. The solvates and/or hydratespreferably exist in crystalline form.

Included within the scope of the invention are complexes such asclathrates, drug-host inclusion complexes wherein, in contrast to theaforementioned solvates, the drug and host are present in stoichiometricor non-stoichiometric amounts. Also included are complexes of the drugcontaining two or more organic and/or inorganic components which may bein stoichiometric or non-stoichiometric amounts. The resulting complexesmay be ionised, partially ionised, or non-ionised. For a review of suchcomplexes, see J Pharm Sci, 64 (8), 1269-1288 by Haleblian (August1975).

The compounds of the invention include compounds of Formula I or IA ashereinbefore defined, polymorphs, and isomers thereof (includingoptical, geometric and tautomeric isomers) as hereinafter defined andisotopically-labelled compounds of Formula I or IA.

The compounds of the present invention may be administered as prodrugs.Thus certain derivatives of compounds of Formula I or IA which may havelittle or no pharmacological activity themselves can, when administeredinto or onto the body, be converted into compounds of Formula I or IAhaving the desired activity, for example, by hydrolytic cleavage. Suchderivatives are referred to as ‘prodrugs’. [Further information on theuse of prodrugs may be found in ‘Pro-drugs as Novel Delivery Systems,Vol. 14, ACS Symposium Series (T Higuchi and W Stella) and‘Bioreversible Carriers in Drug Design’, Pergamon Press, 1987 (ed. E BRoche, American Pharmaceutical Association).]

Prodrugs can, for example, be produced by replacing appropriatefunctionalities present in the compounds of Formula I or IA with certainmoieties known to those skilled in the art as ‘pro-moieties’ asdescribed, for example, in “Design of Prodrugs” by H Bundgaard(Elsevier, 1985).

Some examples of such prodrugs include:

-   (i) where the compound of Formula I or IA contains a carboxylic acid    functionality (—COOH), an ester thereof, for example, replacement of    the hydrogen with (C₁-C₈)alkyl;-   (ii) where the compound of Formula I or IA contains an alcohol    functionality (—OH), an ether thereof, for example, replacement of    the hydrogen with (C₁-C₆) alkanoyloxymethyl; and-   (iii) where the compound of Formula I or IA contains a primary or    secondary amino functionality (—NH₂ or —NHR where R≠H), an amide    thereof, for example, replacement of one or both hydrogens with    (C₁-C₁₀)alkanoyl.

In addition, certain compounds of Formula I or IA may themselves act asprodrugs of other compounds of Formula I or IA.

Compounds of Formula I or IA containing an asymmetric carbon atom canexist as two or more stereoisomers. Where a compound of Formula I or IAcontains an alkenyl or alkenylene group or a cycloalkyl group, geometriccis/trans (or Z/E) isomers are possible. Where the compound contains,for example, a keto or oxime group or an aromatic moiety, tautomericisomerism (‘tautomerism’) can occur. It follows that a single compoundmay exhibit more than one type of isomerism. For example, the followingis illustrative of tautomers of the compounds of Formula I or IA.

Additional example of tautomerism within the scope of the claimedcompounds is the following illustration of guanidine tautomers of thecompounds.

Example of Guanidine Tautomers and Geometric Isomers

Included within the scope of the claimed compounds of the presentinvention are all stereoisomers, geometric isomers and tautomeric formsof the compounds of Formula (I), including compounds exhibiting morethan one type of isomerism, and mixtures of one or more thereof. Alsoincluded are acid addition or base salts wherein the counterion isoptically active, for example, D-lactate or L-lysine, or racemic, forexample, DL-tartrate or DL-arginine.

The present invention includes all pharmaceutically acceptableisotopically-labelled compounds of Formula (I) wherein one or more atomsare replaced by atoms having the same atomic number, but an atomic massor mass number different from the atomic mass or mass number usuallyfound in nature.

Examples of isotopes suitable for inclusion in the compounds of theinvention include isotopes of hydrogen, such as ²H and ³H, carbon, suchas ¹¹C, ¹³C and ¹⁴C, chlorine, such as ³⁶Cl, fluorine, such as ¹⁸F,iodine, such as ¹²³I and ¹²⁵I, nitrogen, such as ¹³N and ¹⁵N, oxygen,such as ¹⁵O, ¹⁷O and ¹⁸O, phosphorus, such as ³²P, and sulphur, such as³⁵S.

Certain isotopically-labelled compounds of Formula (I), for example,those incorporating a radioactive isotope, are useful in drug and/orsubstrate tissue distribution studies. The radioactive isotopes tritium,i.e. ³H, and carbon-14, i.e. ¹⁴C, are particularly useful for thispurpose in view of their ease of incorporation and ready means ofdetection.

Substitution with heavier isotopes such as deuterium, i.e. ²H, mayafford certain therapeutic advantages resulting from greater metabolicstability, for example, increased in vivo half-life or reduced dosagerequirements, and hence may be preferred in some circumstances.

Certain processes for the manufacture of the compounds of this inventionare provided as further features of the invention and are illustrated bythe following reaction schemes. Other processes may be described in theexperimental section. Specific synthetic schemes for preparation of thecompounds of Formula I or IA are outlined below.

As an initial note, in the preparation of the Formula I or IA compoundsit is noted that some of the preparation methods useful for thepreparation of the compounds described herein may require protection ofremote functionality (e.g., primary amine, secondary amine, carboxyl inFormula I or IA precursors). The need for such protection will varydepending on the nature of the remote functionality and the conditionsof the preparation methods. The need for such protection is readilydetermined by one skilled in the art. The use of suchprotection/deprotection methods is also within the skill in the art. Fora general description of protecting groups and their use, see T. W.Greene, Protective Groups in Organic Synthesis, John Wiley & Sons, NewYork, 1991.

For example, certain compounds contain primary amines or carboxylic acidfunctionalities which may interfere with reactions at other sites of themolecule if left unprotected. Accordingly, such functionalities may beprotected by an appropriate protecting group which may be removed in asubsequent step. Suitable protecting groups for amine and carboxylicacid protection include those protecting groups commonly used in peptidesynthesis (such as N-t-butoxycarbonyl, benzyloxycarbonyl, and9-fluorenylmethylenoxycarbonyl for amines and lower alkyl or benzylesters for carboxylic acids) which are generally not chemically reactiveunder the reaction conditions described and can typically be removedwithout chemically altering other functionality in the Formula I or IAcompound.

Those skilled in the art will recognize that there exists a variety ofmethods for preparing thiouracils, including the condensation of athiourea with various carbonyl containing compounds, or by reaction of auracil with a thiating agent such as phosphorous pentasulfide orLawesson's reagent. In forming the thiouracils of the present inventionit is useful to consider the method of construction in order to enhancethe desired compounds over the variety of possible isomers in aregiospecific manner.

The Formula I or IA thiouracil compounds wherein R¹ and R² are asdescribed above may be prepared from the Formula III enamine by acyclization reaction. The Formula III enamine is cyclized to thecorresponding Formula I or IA thiouracil, for example, by reaction withan isothiocyanate such as benzoyl, carboxyethyl or preferably(trimethylsilyl)isothiocyanate (TMSNCS). The reaction proceeds underreaction conditions such as a polar aprotic solvent (e.g., methyltetrahydrofuran, tetrahydrofuran, dioxane, isobutylnitrile or neat inthe isothiocyanate) at a temperature of about 20° C. to about 150° C.,typically about 85° C. (via microwave or thermal heating), for aboutthree hours to about forty-eight hours.

The Formula III enamine may be conveniently prepared from the Formula VIβ-ketoester by reaction with an appropriate R²—NH₂ amine (wherein R² isas described above or wherein reactive functionality in R², such as aprimary amine, is in a suitably a protected form, such as anO-tert-butyl carbamate). For example, the Formula VI β-ketoester isreacted with the R²—NH₂ amine in the presence of a weak acid such asacetic acid in a polar solvent (e.g., methanol, ethanol, isopropanol,toluene or neat in the amine) at a temperature of about 20° C. to about120° C., for about four hours to about seventy-two hours, typicallyabout 80° C. for about 12 hours.

As described above, the Formula VI β-ketoester may be prepared, forexample, from a Formula X methyl ketone, a Formula XV carboxylic acid, aFormula XX aryl halide or other precursors known to those skilled in theart.

The Formula VI β-ketoester is prepared from the Formula X methyl ketoneby carboalkoxylation. For example, the Formula X methyl ketone isreacted with a dialkylcarbonate, preferably dimethyl carbonate, in thepresence of an alkoxide base such as potassium tert-butoxide, in a polarsolvent such as methyl tert-butyl ether or the corresponding alcohol forthe dialkylcarbonate, at a temperature of about 15° C. to about 100° C.,typically ambient temperature, for about four hours to about forty-eighthours, typically twelve hours.

The Formula VI β-ketoester may also be prepared for example from acarboxylic acid. For example, the Formula VI β-ketoester may be preparedfrom an activated carboxylic acid. The Formula XV acid is convenientlyconverted to a corresponding XVII acyl imidazole by reaction with1,1′-carbonyldiimidazole in a polar solvent, typically tetrahydrofuranat a temperature between 0° C. and 100° C., preferably ambienttemperature, for between 1 hour and twenty-four hours, preferably threehours. A solution of the resulting acyl imidazole XVII in a polaraprotic solvent such as tetrahydrofuran is converted to thecorresponding Formula VI β-ketoester by reaction with a solution of anactivated acetate species, such as the enolate of an acetate ester orpreferably ethyl magnesium malonate in a polar aprotic solvent such astetrahydrofuran, at a temperature between −80° C. and 100° C.,preferably ambient temperature, for between one and fourty-eight hours,preferably twelve hours to prepare the corresponding Formula VIβ-ketoester.

Those skilled in the art will recognize that a variety of other methodscan be used to prepare the β-ketoester from an acid.

Those skilled in the art will recognize that the Formula VI β-ketoestersmay also be prepared from esters of Formula XV carboxylic acids, such asmethyl, ethyl, isopropyl, or tert-butyl, preferably the isopropyl esterof Formula XV carboxylic acid by a condensation reaction with anactivated acetate species, such as the enolate of an acetate ester,preferably the enolate of isopropyl acetate, in a polar aprotic solventsuch as tetrahydrofuran, dioxane, or toluene, preferablytetrahydrofuran, at a temperature between −80° C. and 40° C., preferablyambient temperature, for between one and twenty-four hours, preferablytwelve hours to prepare the corresponding Formula VI β-ketoester.

In addition, those skilled in the art will recognize that there are avariety of methods for converting an aryl halide into a β-ketoesterincluding the following exemplary procedures. A Formula XX aryl halide(e.g., an aryl bromide) is combined via a palladium-mediated couplingwith a Formula)(XII β-alkoxyacrylate, such as ethyl 3-ethoxyacrylateemploying a palladium catalyst, typically bis(tri-tert-butylphosphine)palladium (optionally with lithium chloride), in the presence of anamine such as N,N-dicyclohexylmethylamine under an inert atmosphere suchas nitrogen at a temperature of about 90° C. to about 140° C., typicallyat about 110° C., for about four hours to about forty-eight hours,typically 12 hours. The resulting)(XV enolether is converted to thecorresponding Formula VI β-ketoester by treatment with an acid such asaqueous HCl in a polar solvent (e.g., dichloromethane, methanol, aceticacid) at a temperature of about 15° C. to about 40° C., typically atabout ambient, for about thirty minutes to about six hours.

Alternatively, the Formula III enamine may be prepared from the FormulaXXX propiolate via the following two-step reaction.

A Formula XXXII alkyne is coupled with a Formula XXXV boronic acidwherein R¹ is as described above, to prepare the Formula XXX propiolatevia a transition metal mediated coupling. For example, the appropriateR¹-boronic acid in a polar aprotic solvent such as dichloromethane isreacted with cesium carbonate, copper iodide, silver (I) oxide andtert-butyl propiolate at a temperature of about 60° C. to about 100° C.,typically about 80° C., for about 30 minutes to about six hours.

The resulting Formula XXX propiolate is transformed to the correspondingFormula III enamine by amination with the appropriate R²—NH₂ amine(wherein R² is as defined above) in the presence of a weak acid such asacetic acid. The reaction proceeds in a polar solvent such as ethanol orisopropanol at a temperature of about 60° C. to about 100° C. typically,about 80° C. for about 24 hours to about 72 hours.

Theresulting Formula LVII halide undergoes a transition metal mediatedcoupling with the appropriate R¹-metal species (wherein R¹ is as definedabove) by for example reaction with[1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II) and R¹boronic acid (wherein R¹ is as described above) with 1,4 dioxane andaqueous sodium carbonate. The mixture is heated at a temperature ofabout 90° C. to about 150° C., typically by subjecting to microwaveirradiation at 120° C. for about fifteen minutes to about one hour.

Typically thethiouracil is treated with a base such as lithium diisopropylamide in apolar aprotic solvent such as tetrahydrofuran at a temperature of about−20° C. to about −100° C., typically −78° C. Then the solution isallowed to warm to a temperature of about 0° C. to about −25° C.,typically −10° C. for about fifteen minutes to about one hour to preparethe corresponding lithium intermediate followed by cooling to atemperature of about −60° C. to about −80° C., typically −78° C.whereupon the lithium intermediate is reacted with iodine in anappropriate polar aprotic solvent for about 5 minutes to aboutforty-eight hours, typically eight hours.

Particularly when provided as a single dosage unit, the potential existsfor a chemical interaction between the combined active ingredients. Forthis reason, when a Formula I or IA compound and a second therapeuticagent are combined in a single dosage unit they are formulated such thatalthough the active ingredients are combined in a single dosage unit,the physical contact between the active ingredients is minimized (thatis, reduced). For example, one active ingredient may be enteric coated.By enteric coating one of the active ingredients, it is possible notonly to minimize the contact between the combined active ingredients,but also, it is possible to control the release of one of thesecomponents in the gastrointestinal tract such that one of thesecomponents is not released in the stomach but rather is released in theintestines. One of the active ingredients may also be coated with amaterial that affects a sustained-release throughout thegastrointestinal tract and also serves to minimize physical contactbetween the combined active ingredients. Furthermore, thesustained-released component can be additionally enteric coated suchthat the release of this component occurs only in the intestine. Stillanother approach would involve the formulation of a combination productin which the one component is coated with a sustained and/or entericrelease polymer, and the other component is also coated with a polymersuch as a low viscosity grade of hydroxypropyl methylcellulose (HPMC) orother appropriate materials as known in the art, in order to furtherseparate the active components. The polymer coating serves to form anadditional barrier to interaction with the other component.

These as well as other ways of minimizing contact between the componentsof combination products of the present invention, whether administeredin a single dosage form or administered in separate forms but at thesame time by the same manner, will be readily apparent to those skilledin the art, once armed with the present disclosure.

In combination therapy treatment, both the compounds of this inventionand the other drug therapies are administered to mammals (e.g., humans,male or female) by conventional methods.

The Formula I or IA compounds of this invention, their prodrugs and thesalts of such compounds and prodrugs are all adapted to therapeutic useas agents that inhibit myeloperoxidase in mammals, particularly humansand thus are useful for the treatment of the various conditions (e.g.,those described herein) in which such action is implicated.

It is believed that myeloperoxidase is involved in the pathologicoxidation of proteins, lipids and nucleic acids and contributes todysfunctional cholesterol metabolism, tissue damage, and organdysfunction and can induce or contribute to the development ofcardiovascular diseases and associated adverse outcomes.

The disease/conditions that can be treated in accordance with thepresent invention include, but are not limited to, cardiovascularconditions, diabetes (e.g., type II) and diabetic complications,vascular conditions, neuroinflammatory conditions, neurodegenerativeconditions, pain, cancer, sepsis, NASH (non-alcoholicsteatatohepatitis), pulmonary injury and hypertension, renal diseases,and vasculitis syndromes especially those related to ANCA(anti-neutrophil cytoplasmic antibodies) and the like.

Given the positive correlation between activation of the myeloperoxidasewith the development of cardiovascular and associateddisease/conditions, Formula I or IA compounds of this invention, theirprodrugs and the salts of such compounds and prodrugs, by virtue oftheir pharmacologic action, are useful for the prevention, arrestmentand/or regression of atherosclerosis and its associated disease states.

It is believed that MPO exhibits pro-atherogenic biological activityduring the evolution of cardiovascular disease. Furthermore, it has beenobserved that MPO-generated oxidants reduce the bioavailability ofnitric oxide, an important vasodilator. Additionally, it has been shownthat MPO plays a role in plaque destabilization by causing theactivation of metalloproteinases, leading to a weakening of the fibrouscap of the plaques and subsequent plaque destabilization and rupture.Given these wide-ranging effects of MPO, MPO has thus been implicated ina wide variety of cardiovascular diseases.

Cardiovascular conditions include, but are not limited to coronary heartdisease, acute coronary syndrome, ischaemic heart disease, first orrecurrent myocardial infarction, secondary myocardial infarction, non-STsegment elevation myocardial infarction, or ST segment elevationmyocardial infarction, ischemic sudden death, transient ischemic attack,peripheral occlusive arterial disease, angina, atherosclerosis,hypertension, heart failure (such as congestive heart failure),diastolic dysfunction (such as left ventricular diastolic dysfunction,diastolic heart failure, and impaired diastolic filling), systolicdysfunction (such as systolic heart failure with reduced ejectionfraction), atrial fibrillation, arrhythmia (ventricular), ischemia,hypertrophic cardiomyopathy, sudden cardiac death, myocardial andvascular fibrosis, impaired arterial compliance, myocardial necroticlesions, vascular damage, left ventricular hypertrophy, decreasedejection fraction, cardiac lesions, vascular wall hypertrophy,endothelial thickening, fibrinoid necrosis of coronary arteries, adverseremodeling, stroke, and the like. Also, included are venous thrombosis,deep vein thrombosis, thrombophlebitis, arterial embolism, coronaryarterial thrombosis, cerebral arterial thrombosis, cerebral embolism,kidney embolism, pulmonary embolism, and thrombosis resulting from (a)prosthetic valves or other implants, (b) indwelling catheters, (c)stents, (d) cardiopulmonary bypass, (e) hemodialysis, or (f) otherprocedures in which blood is exposed to an artificial surface thatpromotes thrombosis. It is noted that thrombosis includes occlusion(e.g., after a bypass) and reocclusion (e.g., during or afterpercutaneous transluminal coronary angioplasty).

Cardiovascular complications of type 2 diabetes are associated withdeleterious levels of MPO, accordingly, the compounds of the presentinvention may be used to treat diabetes and diabetic complications suchas macrovascular disease, hyperglycemia, metabolic syndrome, impairedglucose tolerance, hyperuricemia, glucosuria, cataracts, diabeticneuropathy, diabetic nephropathy, diabetic retinopathy, obesity,dyslididemia, hypertension, hyperinsulinemia, and insulin resistancesyndrome.

In addition, linkage of myeloperoxidase activity to disease has beendemonstrated in neuroinflammatory and neurodegenerative conditions.Therefore, the compounds of the present invention are particularlyindicated for use in the treatment of neuroinflammatory andneurodegenerative conditions (i.e., disorders or diseases) in mammalsincluding humans such as multiple sclerosis, migraine; epilepsy;Alzheimer's disease; Parkinson's disease; brain injury; stroke;cerebrovascular diseases (including cerebral arteriosclerosis, cerebralamyloid angiopathy, hereditary cerebral hemorrhage, and brainhypoxia-ischemia); cognitive disorders (including amnesia, seniledementia, HIV associated dementia, Alzheimer's associated dementia,Huntington's associated dementia, Lewy body dementia, vascular dementia,drug related dementia, delirium, and mild cognitive impairment); mentaldeficiency (including Down syndrome and fragile X syndrome); sleepdisorders (including hypersomnia, circadian rhythm sleep disorder,insomnia, parasomnia, and sleep deprivation) and psychiatric disorders(such as anxiety (including acute stress disorder, generalized anxietydisorder, social anxiety disorder, panic disorder, post-traumatic stressdisorder and obsessive-compulsive disorder); factitious disorder(including acute hallucinatory mania); impulse control disorders(including compulsive gambling and intermittent explosive disorder);mood disorders (including bipolar I disorder, bipolar II disorder,mania, mixed affective state, major depression, chronic depression,seasonal depression, psychotic depression, and postpartum depression);psychomotor disorder; psychotic disorders (including schizophrenia,schizoaffective disorder, schizophreniform, and delusional disorder);drug dependence (including narcotic dependence, alcoholism, amphetaminedependence, cocaine addiction, nicotine dependence, and drug withdrawalsyndrome); eating disorders (including anorexia, bulimia, binge eatingdisorder, hyperphagia, and pagophagia); and pediatric psychiatricdisorders (including attention deficit disorder, attentiondeficit/hyperactive disorder, conduct disorder, and autism) in a mammal,preferably a human, comprising administering to said mammal atherapeutically effective amount of a compound of Formula I or IA orpharmaceutically acceptable salt thereof.

The following protocols may of course be varied by those skilled in theart.

MPO Amplex Red Activity Assay.

MPO peroxidase activity was measured by monitoring the formation ofresorufin generated from the oxidation of Amplex Red(10-Acetyl-3,7-dihydroxyphenoxazine) (Invitrogen, Carlsbad, Calif.) byMPO (Gomes, Fernandes et al. 2005). Assay mixtures (100 μL total volume)contained 50 mM NaPi pH 7.4, 150 mM NaCl, 1 mM DTPA(diethylenetriaminepentaacetic acid), 2% DMSO, 2 μM H₂O₂, 30 μM AmplexRed and the reaction was initiated by the addition of 100 pM MPO(purified from human polynuclear leukocytes and purchased fromCalbiochem/EMD Biosciences, Gibbstown, N.J.). All assays were performedin 96-well, half-area, black, nonbinding surface, polystyrene plates(Corning) and the production of resorufin (excitation 530 nm, emission580 nm) was monitored every 20 sec on a Spectramax M2 MicroplateSpectrophotometer (Molecular Devices, Palo Alto, Calif.) equipped withSoftmax Pro software (Molecular Devices, Palo Alto, Calif.). Reactionsto determine the background reaction rate consisted of all assaycomponents and 4 μL of 500 unit/mL bovine catalase (Sigma) in 50 mM KPipH 7.0. The background rate was subtracted from each reaction progresscurve. All data was analyzed using non-linear regression analysis inMicrosoft Excel and Kaleidagraph (Synergy Software).

To determine inhibitor potency (k_(inact)/K_(I)) against MPO, the first600 sec of the reaction progress curves were fit to equation 1, whereV_(o) is the initial rate in RFU/sec and t is time in seconds, to obtainthe first order rate constant for enzyme inactivation (k_(obs)) at eachinhibitor concentration.

$\begin{matrix}{{Product} = {\frac{V_{0}}{k_{obs}}\mspace{14mu}\lbrack {1 - {\exp( {{- k_{obs}}t} )}} \rbrack}} & (1)\end{matrix}$Equation 1 is a variation of the standard equation for slow bindinginhibition where the steady state velocity (V_(s)) is set to zero. Eachk_(obs) value was corrected for auto-inactivation of the enzyme bysubtracting the k_(obs) value for the uninhibited reaction. Thecorrected k_(obs) values were then plotted versus inhibitorconcentration ([I]) and fit to equation 2

$\begin{matrix}{k_{obs} = \frac{k_{inact}\lbrack I\rbrack}{K_{I} + \lbrack I\rbrack}} & (2)\end{matrix}$where k_(inact) is the maximal rate of inactivation and K_(I) is theinhibitor concentration that yields half the rate of maximalinactivation (Copeland 2005).Table 1 and (1A) below provides the myeloperoxidase inhibitory activityfor the Examples below in accordance with the above-described assay.

TPO Amplex Red Activity Assay

TPO activity was measured using the same assay as MPO with 2 μM H₂O₂, 30μM Amplex Red and the reactions were initiated with 1.3 μg of proteinfrom HEK293 cell membranes expressing human TPO. The cDNA encoding 933amino acids of the full length human TPO was cloned into the inducibleexpression vector pcDNA5/frt/to (InVitrogen), stable 293 clones wereselected using 100 ug/ml of hygromycin and 15 ug/ml blasticidine in DMEMw/10% FBS. When cells reached 50-60% confluence, TPO expression wasinduced in medium containing all of above plus 10 ug/ml doxicycline and5 ug/ml hemin (Sigma). Membranes were isolated from HEK293hTPO byharvesting the cells in PBS. The cells were pelleted at 1000×g for 5minutes at 4° C., resuspended in homogenization buffer (1 mM sodiumbicarbonate, pH 7.4) containing EDTA-Free protease inhibitor (Roche),and incubated on ice for 10 minutes followed by Dounce homogenization.Nuclei and unlysed cells were removed by pelleting at 1000×g for 10minutes at 4° C. The supernatent was then centrifuged at 25,000×g for 20minutes at 4° C. The pellet was resuspended in homogenization buffer andcentrifuged again at 25,000×g for 20 minutes at 4° C. The final pelletwas resuspended in storage buffer (50 mM Tris pH 7, 150 mM NaCl)containing protease inhibitors as described above. Membraneconcentration was determined using the BCA Protein Assay (Pierce). TPOactivity was measured using the Amplex Red assay as described above.Aliquots were made based on the activity accordingly and stored at −80°C.

The IC₅₀ values were determined by plotting the initial rates (from thefirst 200 sec of each reaction progress curve) as percentage ofinhibition relative to the uninhibited (DMSO) reaction as a function ofinhibitor concentration. The data were fit to equation 3

$\begin{matrix}{y = \frac{100}{1 + ( {x\text{/}{IC}_{50}} )^{z}}} & (3)\end{matrix}$where IC₅₀ is the inhibitor concentration at 50% inhibition and z is theHill slope (the slope of the curve at its inflection point).

Human Whole Blood Assay for Irreversible Inhibition of MPO

To measure the inhibition of MPO activity in a biological system in thepresent invention, bioassays are performed with human whole blood thatis collected from medication-free, human volunteers in heparin treatedtubes (APP Pharmaceuticals, LLC, cat # NDC#63323-047-10, #4710). Bloodis aliquoted and treated with different concentrations of the MPOinhibitor or vehicle control and co-treated with or without bacteriallipopolysaccharide (LPS, InVivogen, cat# tlrl-pelps) to stimulate bloodleukocytes to simultaneously generate H₂O₂ (a required MPO substrate)and the release of MPO. After 4 hour incubation at room temperature theplasma fraction is collected following a 2000×g centrifugation at 4° C.

The plasma fraction is divided into two for analysis of total MPO andactive MPO. The total MPO content is determined using a standardsandwich ELISA (capture and detection antibodies: Cell Sciences, Cat#HP9048, and Cell Sciences, Cat# HM2164, clone 266-6K1) and calculatedrelative to a standard curve of purified MPO (myeloperoxidase,Calbiochem, cat#475911) that is prepared by dilution in the autologousdonor plasma. The MPO activity is determined by capturing the total MPOfrom plasma using the capture step as described for the ELISA method.After washing unbound plasma material including unreacted MPO inhibitor,MPO reaction substrates are added [H₂O₂ (2 uM) and Amplex Red(Invitrogen, Cat# A12222)] and the Vmax of the MPO-catalyzed conversionof the Amplex Red substrate to resorufin is determined by measuring theincrease in fluorescence (excitation 530 nM, emission 580 nm) using afluorescent plate reader in a kinetic analysis. The MPO activity of thecaptured material is compared to that obtained with a standard curve ofpurified MPO (myeloperoxidase, Calbiochem, cat#475911) that was preparedin autologous donor plasma. The percent of ‘active’ myeloperoxidase foreach sample is calculated from the ratio of the active myeloperoxidasein the Amplex Red assay and the total myeloperoxidase from the ELISA foreach sample. A dose response curve of the MPOi concentration versus MPOactivity is then plotted to determine the IC50 value.

Administration of the compounds of this invention can be via any methodwhich delivers a compound of this invention systemically and/or locally.These methods include oral routes, parenteral, intraduodenal routes,buccal, intranasal etc. Generally, the compounds of this invention areadministered orally, but parenteral administration (e.g., intravenous,intramuscular, subcutaneous or intramedullary) may be utilized, forexample, where oral administration is inappropriate for the target orwhere the patient is unable to ingest the drug.

For administration to human patients, an oral daily dose of thecompounds herein may be in the range 1 mg to 5000 mg depending, ofcourse, on the mode of and frequency of administration, the diseasestate, and the age and condition of the patient, etc. An oral daily doseis in the range of 3 mg to 2000 mg may be used. A further oral dailydose is in the range of 5 mg to 1000 mg. For convenience, the compoundsof the present invention can be administered in a unit dosage form.

The unit dosage form, for example, may bea tablet or capsule containing about 0.1, 0.5, 1, 5, 10, 15, 20, 25, 30,35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100, 125, 150, 175,200, 250, 500, or 1000 mg of the compound of the present invention. Thetotal daily dose may be administered in single or divided doses and may,at the physician's discretion, fall outside of the typical ranges givenherein.

For administration to human patients, an infusion daily dose of thecompounds herein may be in the range 1 mg to 2000 mg depending, ofcourse, on the mode of and frequency of administration, the diseasestate, and the age and condition of the patient, etc. A further infusiondaily dose is in the range of 5 mg to 1000 mg. The total daily dose maybe administered in single or divided doses and may, at the physician'sdiscretion, fall outside of the typical ranges given herein.

These compounds may also be administered to animals other than humans,for example, for the indications detailed above. The precise dosageadministered of each active ingredient will vary depending upon anynumber of factors, including but not limited to, the type of animal andtype of disease state being treated, the age of the animal, and theroute(s) of administration.

A dosage of the combination pharmaceutical agents to be used inconjuction with the Formula I or IA compounds is used that is effectivefor the indication being treated. Such dosages can be determined bystandard assays such as those referenced above and provided herein. Thecombination agents may be administered simultaneously or sequentially inany order.

These dosages are based on an average human subject having a weight ofabout 60 kg to 70 kg. The physician will readily be able to determinedoses for subjects whose weight falls outside this range, such asinfants and the elderly.

Dosage regimens may be adjusted to provide the optimum desired response.For example, a single bolus may be administered, several divided dosesmay be administered over time or the dose may be proportionally reducedor increased as indicated by the exigencies of the therapeuticsituation. It is especially advantageous to formulate parenteralcompositions in dosage unit form for ease of administration anduniformity of dosage. Dosage unit form, as used herein, refers tophysically discrete units suited as unitary dosages for the mammaliansubjects to be treated; each unit containing a predetermined quantity ofactive compound calculated to produce the desired therapeutic effect inassociation with the required pharmaceutical carrier. The specificationfor the dosage unit forms of the invention are dictated by and directlydependent on (a) the unique characteristics of the chemotherapeuticagent and the particular therapeutic or prophylactic effect to beachieved, and (b) the limitations inherent in the art of compoundingsuch an active compound for the treatment of sensitivity in individuals.

Thus, the skilled artisan would appreciate, based upon the disclosureprovided herein, that the dose and dosing regimen is adjusted inaccordance with methods well-known in the therapeutic arts. That is, themaximum tolerable dose can be readily established, and the effectiveamount providing a detectable therapeutic benefit to a patient may alsobe determined, as can the temporal requirements for administering eachagent to provide a detectable therapeutic benefit to the patient.Accordingly, while certain dose and administration regimens areexemplified herein, these examples in no way limit the dose andadministration regimen that may be provided to a patient in practicingthe present invention.

It is to be noted that dosage values may vary with the type and severityof the condition to be alleviated, and may include single or multipledoses. It is to be further understood that for any particular subject,specific dosage regimens should be adjusted over time according to theindividual need and the professional judgment of the personadministering or supervising the administration of the compositions, andthat dosage ranges set forth herein are exemplary only and are notintended to limit the scope or practice of the claimed composition. Forexample, doses may be adjusted based on pharmacokinetic orpharmacodynamic parameters, which may include clinical effects such astoxic effects and/or laboratory values. Thus, the present inventionencompasses intra-patient dose-escalation as determined by the skilledartisan. Determining appropriate dosages and regiments foradministration of the chemotherapeutic agent are well-known in therelevant art and would be understood to be encompassed by the skilledartisan once provided the teachings disclosed herein.

The present invention further comprises use of a compound of Formula Ior IA for use as a medicament (such as a unit dosage tablet or unitdosage capsule). In another embodiment, the present invention comprisesthe use of a compound of Formula I or IA for the manufacture of amedicament (such as a unit dosage tablet or unit dosage capsule) totreat one or more of the conditions previously identified in the abovesections discussing methods of treatment.

A pharmaceutical composition of the invention may be prepared, packaged,or sold in bulk, as a single unit dose, or as a plurality of single unitdoses. As used herein, a “unit dose” is discrete amount of thepharmaceutical composition comprising a predetermined amount of theactive ingredient. The amount of the active ingredient is generallyequal to the dosage of the active ingredient which would be administeredto a subject or a convenient fraction of such a dosage such as, forexample, one-half or one-third of such a dosage.

The compounds described herein may be administered as a formulationcomprising a pharmaceutically effective amount of a compound of FormulaI or IA, in association with one or more pharmaceutically acceptableexcipients including carriers, vehicles and diluents. The term“excipient” herein means any substance, not itself a therapeutic agent,used as a diluent, adjuvant, or vehicle for delivery of a therapeuticagent to a subject or added to a pharmaceutical composition to improveits handling or storage properties or to permit or facilitate formationof a solid dosage form such as a tablet, capsule, or a solution orsuspension suitable for oral, parenteral, intradermal, subcutaneous, ortopical application. Excipients can include, by way of illustration andnot limitation, diluents, disintegrants, binding agents, adhesives,wetting agents, polymers, lubricants, glidants, stabilizers, substancesadded to mask or counteract a disagreeable taste or odor, flavors, dyes,fragrances, and substances added to improve appearance of thecomposition. Acceptable excipients include (but are not limited to)stearic acid, magnesium stearate, magnesium oxide, sodium and calciumsalts of phosphoric and sulfuric acids, magnesium carbonate, talc,gelatin, acacia gum, sodium alginate, pectin, dextrin, mannitol,sorbitol, lactose, sucrose, starches, gelatin, cellulosic materials,such as cellulose esters of alkanoic acids and cellulose alkyl esters,low melting wax, cocoa butter or powder, polymers such aspolyvinyl-pyrrolidone, polyvinyl alcohol, and polyethylene glycols, andother pharmaceutically acceptable materials. Examples of excipients andtheir use may be found in Remington's Pharmaceutical Sciences, 20thEdition (Lippincott Williams & Wilkins, 2000). The choice of excipientwill to a large extent depend on factors such as the particular mode ofadministration, the effect of the excipient on solubility and stability,and the nature of the dosage form.

The compounds herein may be formulated for oral, buccal, intranasal,parenteral (e.g., intravenous, intramuscular or subcutaneous) or rectaladministration or in a form suitable for administration by inhalation.The compounds of the invention may also be formulated for sustaineddelivery.

Methods of preparing various pharmaceutical compositions with a certainamount of active ingredient are known, or will be apparent in light ofthis disclosure, to those skilled in this art. For examples of methodsof preparing pharmaceutical compositions see Remington's PharmaceuticalSciences, 20th Edition (Lippincott Williams & Wilkins, 2000).

Pharmaceutical compositions according to the invention may contain0.1%-95% of the compound(s) of this invention, preferably 1%-70%. In anyevent, the composition to be administered will contain a quantity of acompound(s) according to the invention in an amount effective to treatthe disease/condition of the subject being treated.

Since the present invention has an aspect that relates to the treatmentof the disease/conditions described herein with a combination of activeingredients which may be administered separately, the invention alsorelates to combining separate pharmaceutical compositions in kit form.The kit comprises two separate pharmaceutical compositions: a compoundof Formula I or IA a prodrug thereof or a salt of such compound orprodrug and a second compound as described above. The kit comprises ameans for containing the separate compositions such as a container, adivided bottle or a divided foil packet. Typically the kit comprisesdirections for the administration of the separate components. The kitform is particularly advantageous when the separate components arepreferably administered in different dosage forms (e.g., oral andparenteral), are administered at different dosage intervals, or whentitration of the individual components of the combination is desired bythe prescribing physician.

An example of such a kit is a so-called blister pack. Blister packs arewell known in the packaging industry and are being widely used for thepackaging of pharmaceutical unit dosage forms (tablets, capsules, andthe like). Blister packs generally consist of a sheet of relativelystiff material covered with a foil of a preferably transparent plasticmaterial. During the packaging process recesses are formed in theplastic foil. The recesses have the size and shape of the tablets orcapsules to be packed. Next, the tablets or capsules are placed in therecesses and the sheet of relatively stiff material is sealed againstthe plastic foil at the face of the foil which is opposite from thedirection in which the recesses were formed. As a result, the tablets orcapsules are sealed in the recesses between the plastic foil and thesheet. Preferably the strength of the sheet is such that the tablets orcapsules can be removed from the blister pack by manually applyingpressure on the recesses whereby an opening is formed in the sheet atthe place of the recess. The tablet or capsule can then be removed viasaid opening.

It may be desirable to provide a memory aid on the kit, e.g., in theform of numbers next to the tablets or capsules whereby the numberscorrespond with the days of the regimen which the tablets or capsules sospecified should be ingested. Another example of such a memory aid is acalendar printed on the card, e.g., as follows “First Week, Monday,Tuesday, etc. . . . Second Week, Monday, Tuesday, . . . ” etc. Othervariations of memory aids will be readily apparent. A “daily dose” canbe a single tablet or capsule or several pills or capsules to be takenon a given day. Also, a daily dose of Formula I or IA compound canconsist of one tablet or capsule while a daily dose of the secondcompound can consist of several tablets or capsules and vice versa. Thememory aid should reflect this.

In another specific embodiment of the invention, a dispenser designed todispense the daily doses one at a time in the order of their intendeduse is provided. Preferably, the dispenser is equipped with amemory-aid, so as to further facilitate compliance with the regimen. Anexample of such a memory-aid is a mechanical counter which indicates thenumber of daily doses that has been dispensed. Another example of such amemory-aid is a battery-powered micro-chip memory coupled with a liquidcrystal readout, or audible reminder signal which, for example, readsout the date that the last daily dose has been taken and/or reminds onewhen the next dose is to be taken.

Also, as the present invention has an aspect that relates to thetreatment of the disease/conditions described herein with a combinationof active ingredients which may be administered jointly, the inventionalso relates to combining separate pharmaceutical compositions in asingle dosage form, such as (but not limited to) a single tablet orcapsule, a bilayer or multilayer tablet or capsule, or through the useof segregated components or compartments within a tablet or capsule.

General Experimental Procedures

All chemicals, reagents and solvents were purchased from commercialsources when available and used without further purification. Protonnuclear magnetic spectroscopy (¹H NMR) was recorded with 400 and 500 MHzVarian spectrometers. Chemical shifts are expressed in parts per milliondownfield from tetramethylsilane. The peak shapes are denoted asfollows: s, singlet; d, doublet; t, triplet; q, quartet; m, multiplet;br s, broad singlet. Mass spectrometry (MS) was performed viaatmospheric pressure chemical ionization (APCI) or electron scatter (ES)ionization sources. Observed mass (Obs Mass) reported in the Tablescorrespond to the exact mass of the parent molecule plus one, unlessotherwise noted. Silica gel chromatography was performed primarily usinga medium pressure Biotage or ISCO systems using columns pre-packaged byvarious commercial vendors including Biotage and ISCO. Microanalyseswere performed by Quantitative Technologies Inc. and were within 0.4% ofthe calculated values. The terms “concentrated” and “evaporated” referto the removal of solvent at reduced pressure on a rotary evaporatorwith a bath temperature less than 60° C. The abbreviation “min” and “h”stand for “minutes” and “hours” respectively.

Powder X-Ray Diffraction

Powder diffraction analysis was conducted using a Bruker D8diffractometer equipped with a Cu radiation source, fixed slits(divergence=1.0 mm, anti-scatter=0.6 mm, and receiving=0.6 mm) and ascintillation counter detector. Data was collected in the Theta-Thetagoniometer at the Cu wavelength Kα_(i)=1.54056 Å from 3.0 to 40.0degrees 2-Theta using a step size of 0.040 degrees and a step time of2.0 second. X-ray tube voltage and amperage were set at 40 kV and 40 mArespectively. Samples were prepared by placement in a Nickel Disk(Gasser & Sons, Inc. Commack, N.Y.) and rotated during data collection.Data were collected and analyzed using Bruker DIFFRAC Plus software(Version 2.6).
